Flat Tubes.....but no leaks

Hi All
I have a Tornado of late 90's build. She has a hard life but is loved and all in all her tubes are in okay condition. They are PU/PVC rather than Hypalon and recently she has been going flat.

I have replaced two valves which I believe may have been the cause. No difference. I have checked for air leaks around them but no signs. I have pumped it up hard and sprayed water and sqoosh and there are no obvious signs of leakage. Has anyone ever experienced this before?

If I pump her up hard in the morning she is needing pumped up again by 3pm or so, so I would expect this air leak to be obvious.

Cheers

Is this happening on all the chambers? If it is the bulkheads will have blown. The seam on these boats is behind the running strake which will make it hard to find leaks.

Seams are the most likely culprit, the material is so good the glue goes first.
